From 2077eebf7d8bf20b36524de45851e28111a60c52 Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Wed, 15 Oct 2014 14:33:20 -0700 Subject: [PATCH] ipv4: call __ip_options_echo() in cookie_v4_check() commit 971f10eca186cab238c49da ("tcp: better TCP_SKB_CB layout to reduce cache line misses") missed that cookie_v4_check() still calls ip_options_echo() which uses IPCB(). It should use TCPCB() at TCP layer, so call __ip_options_echo() instead.
